Exciting!! I would say…
- a short goodbye and focus on the positive. End with “I’ll see you at the bus stop/car pick” or wherever
- the books The Invisible String and The Kissing Hand
- have them practice opening their lunchboxes, unpacking their snack etc
- shoes without laces unless they can tie their own shoes
- leak proof water bottle-truly leak proof
- meet the other parents as quickly as possible!
